Default Can anyone identify this part

I have a Furuno 6100 on a Mako I purchased a few months back. I wasn't getting a good reading on my Depthfinder on Saturday. I was looking in my bilge area and I see two things. 1 is my thru hull transducer. The second is this disk looking thing. Being this hull is older. I'm not sure what this could be. Can someone help me identify it. The part is not secured. I actually picked it up and moved it around for the photos too.







I appreciate the help with this.

The nastiest bilge contest. It may have a part number on it.

I have to agree. I understand though, that boat bilges can be cleaned up. Here's mine:

As for the "disk looking thing", the black thing with a cable on it looks like a transducer for a depth sounder. If you're not getting a good reading, it is because this should not be flopping around in the bilge (assuming that it is the transducer that is connected to your system), it should be glued to the inside of the hull surface in a location that is parallel to the water surface and solid fiberglass.

Sure looks like transducer that broke away from being bedding compound. Had one break away from an epoxy bedding on an old bass boat.

Actually, that is the top to an "older" Airmar P79 in hull transducer...yours was OEM on Noahs Ark.
Your are just missing the tank.




Newer version.

I'm going to have problems sleeping tonight...couldn't you have titled your post "adult content" or "from the morgue" or something similar?

Disgusting state of deferred-maintenance...I prefer the "bristol" condition, myself...

i know the bilge isn't pretty, but as I said, I just picked this boat up. Its was not maintained like it should have been when it comes to cleaning. I took a few other pics that maybe someone can identify. I'm sure its the transducer, but there are no markings identifing what brand it is. I'm just trying to find out if there are any missing parts. Thanks again

Its only part of the transducer....that goes to an old P79.
Just toss it...It's reliability is suspect and a new one is only about $100. or so depending on the sonar type.

The rest of the P79 (the cup) may still be in the boat, glued down where it's supposed to be.

From the original post:

...... I wasn't getting a good reading on my Depthfinder on Saturday. .............
The OP didn't say if he got good readings in the past and then they stopped or if he has had problems since he bough the boat. We don't know if his depth sounder is connected to this transducer or if a previous owner abandoned the one in the photo and installed another one somewhere else.

The P79 transducer is like any other transducer in that it can just be set on or glued to the hull surface. The liquid filled cup is just to allow for angled hulls. Before permanently installing mine, I covered the bottom with KY jelly and set it on the inside of the hull with a sandbag to hold it in place. It stayed that way for a year or more because I put the rest of the assembly in a "safe place" and forgot where I put it. It worked fine the entire time but I have a flat horizontal surface on my hull.
